2. Description of The Prior Art

Many people who drive in snow weather conditions are often required to have chains for their vehicle's tires. After the chains are used and removed from the vehicle, they are usually very wet because of the snow and slush. People usually remove the chains and store them in the trunk of the vehicle or place them back in the original container. Since the chains are still wet, they clearly rust within a matter of a few days or weeks and by the time they are to be subsequently used, the chains are frequently rusted. The rusted chains are very difficult to install and are frequently replaced with new snow chains. This is not practical.
